T o all whom t mag/concern.'

ABe it known that I, FRANCIS E. YOUNG, a citizen of, the United States, and a resident of Boston, in Vthe county of Suffolk and State of Massachusetts, have invented an the following description, in connection withthe accompany-ing drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to spray nozzles intended for'use in various relations.

Alnorder thatthe' principle'of the inveni. tion maybe readily understood, have disclosed a single embodiment'thereof in the accompanying drawings, whereinm Figure I is a vertical, sectionalyiew ofa spray nozzle constructedin accordance with my invention; Fig. 2.is ahorizontal section upon the line 2 2 of Fig. 1; and Fig. 3 iS-a side elevation of one of the'liquid distributing elements of the nozzle.

The nozzle herein disclosed is adapted for `use in many .different relations, but isv particularly Vintended for use ,as a lawn sprinkler.' To that end, it is' provided with a-heavy,v hollow,-metallic-base 1 having a removable, threaded plug 2 through the bottom, permitting access thereto, and with a threaded opening 3, to which a hose or other supply pipe may` be attached. The said base has a flat-tened bottom 4 of considerable area, so` that the structure cannot readily be overturned. The shape of said base may be varied withi'nthe scope of my invention.

. The said base is herein represented as. provided vwith :in-upright neck portion 5, herein Shown as provided with an annular flange (3 and an externally threaded nipple 7 adapted to receive thereon a member 8 internally threaded as indicated at 9, said member-B constituting a portion of the nozzle proper.

The shell or member 8 isprovided with a transverse web 10 somewhat widened at its middle portion 11 and there internally threaded, as represented at 12, for the reccption Vof' an axial stem or plug 13, herein shown as having a solid, lower end of reduced diameter, and an upper portion 1l of increased diameter providing a shoulder 15 adaptedto seat upon said web 10. -Preer- Q ablyp-'from the shoulder 15 to a pointV near thlipper end of said stem or plug, it is propurpose.

vided with a pfeferabiyfmdiai slot. 'is 'in Specilcpationvof Letters Patent. Pzjljenled luig. 29, 1916.

. communication at .its lower 1 endV With-,the in-.

terior of the shell Or mmber8,land hence j n with the interior of the base 1. The said slot 1G is herein represented as Acurved Or` arcuate in vertical section and as `terminating at a point Slightly below'thlextreme upper edge of Sald stein or plug, and herein at substantially the point 17. The portionA A 1li of the Said stem or plug is externally threaded as indicated at 18 for the'receptionof a secondary shell' 19 and is also provided with external helical .grooves'2'0 for thedistribution of the water or other liquidto be 'Y discharged from the nozzle. vBet'weenthe upper end ofthe threaded portion 1 8 and the helical grooves 20, the' s aidstem or plug is of reduced.'diaxrueter,` as indicated at21. The said stem or plug 13 isV provided With anaxial passage 22, which isin communication withthe lslot-16.

into contact with' or to Ibe spaced from the lupper edge 2G of the. Shell orimember 8.

Said secondary shell- 19' is formed .to pro- ,vide a chamber 27,. herein represented as preferably form the separate vanes 31 by strilcin'g'them up from a ring 32. The "said vanos and the ring may be formed of -some Suitable sheet metal, such as brass, the vanes being struck up fromlthe ring which may be circumferential and radially sli-tted for that As herein shown, I proyide six vanes each extending a correspondingdistance circumferentially about the ring. In order to position the said ring with its Yanes, l preferal'ily -provide itwvith an inwardly extending lug 33, which is adapted to be received within the Slot 16. Said ring is therefore capable of axial movement in the operation of the .nozzle and may be readily removedupon removal ofthe lsec-Y ondary shell 19. It is, however, held from Vhile these vanes may-be integral"A with some otherportion' of the Structure, IV

circumferential movement by the said lug' 'I5A vThe secondary. shell 19 is internally= threaded as represented-at 23 and is prof vided-with an annu-lar flange 24, the underA 'face 2,5 of which is adapted to vbe brought 33. AnY outwardly flaring conical sheet of fluid is discharged vbetween the shells 8 and The vanes 31 tend to impart to the particles of fluid motion in paths diverging from the longitudinal axis of the nozzle,

and oblique to the elements of the cone. The helical. grooves may be formed upon .the axial-stern or plug 13, orif desired. they may be. formed upon the inner surface o f the secondary shell 19.

l Inoperation, Va pluralitydof streams are admitted'into-the secondaryshell 19 and are thoroughlymixed therein prior totheir dis charge through the axial passage 29, so that in this embodiment of my invention, the spray as 'discharged is oli-substantially homogeneous structure throughout. The -spray Adischarged betiveentlief'tivo shells 8 and 19 may be 'varied inV amount by Aadjusting the latter shell. l V

"The base 1, whichv is relatively large and heavy and is'preferably Aof circular form in 'Across section, is substantially non-tipping.

-Because 0f its' flatbottoiii 4;,.it may be "readily placed at any desired'point upon a tation, the .scope of the invei'itio'n being set forth iii .the following-claii'ns.
